Application filed August 25, 1915. Serial No, 4735128.

To all whom it may concern:

Be it known that I, I'IOWARD D. Coon, a citizen. of the United States,residing at Lorain, in the county of Lorain, and State of Ohio, haveinvented certain new and useful Improvements in Platel iling Mechanisms,of which the following is a specific: tion. 7 v

lhis invention relates to means employed in handling thin, fiat,flexible rolled metal products such as pipe skelp, sheet and tin bars,universal plates and similar materials of considerable length andrelatively narrow width, in piling two or more pieces or lengths of suchmaterials, one on top of another, and the invention more particularlyrelates to piling such rolled metal materials one on another, to enablea plurality of pieces of such materials to be sheared simul taneously tolength or into a series of short pieces of predetermined or measuredlength.

Pipe skelp, sheet and tin bars, universal plates and like rolledmaterials are rolled, in modern rolling mills in pieces of very greatlength, and much longer than is usable in fabricating the rolled platesor materials into other articles. In addition to cropping the ends ofsuch materials after the rolling operation, it is also necessary to cutthe rolled material into several shorter pieces, while in the case ofsheet and tin bars, the multiple length bars formed in rolling are cutup into. a multiplicity of small pieces of small length in preparationfor rolling on hot mills into sheets and plates.

One object of my invention is to provide apiling mechanism of'iinprovedconstruction having novel means whereby two or more pipe skelp, multiplelength tin or sheet bars, or similar long, thin, flexible. materials areautomatically piled one on top of the other or others while thematerials are being moved lengthwise on a roller feed table orequivalent conveyer into position to be sheared or cut to length.

Another object of this invention is to provide a piling mechanism havingmeans whereby a plurality of pieces of thin flexible rolled material aremechanically assembledinto position enabling a plurality o-fpieces ofsuch material being sheared t 'ansverscly of the length thereof with ashear having cutting knives or shear blades of less width than thecombined Width of two pieces of the materials being sheared or severedfurther object of the invention is the Referring now to the drawingsforming.

part of this specification Figure 1 is a plan showing a piling mechanismconstructed and arranged and adapted for use in connection with a shearand roller feed table in accordance with my invention. Fig. 2 is asectional side elevation of the piling mechanism of Fig. 1, the sectionbeing taken on the line H 11 of Fig. 1. Fig. 3 isa sectional endelevation showing the construction of the vertical rollers forming partof my improved piling mechanism.

In the accompanying drawings, the numeral 2 designates a shear of thetype having shear knives which are relatively movable vertically.Positioned at the rear or entrance side of the shear is a pair ofhorizontal pinch rollers 8, 4- by which the piled slrelp or plates arefed forwardly between the shear knives into position for the severing orshearing operations. The pinch rollers 8 and l are relatively movable inthe bearings 5, therefor to suit theconditions imposed by the combinedthickness of the piled bars and at least one of the pinch rollers ispositively driven in the usual. known manner by a suitable motor shown)operatively connected to the roller shaft 6.

Located behind the. shear 2, at a suitable distance in the rear of thepinch rollers 3 and at is a feed roller table or conveyor of the usualconstruction havingteed rollers 7, rotatably mounted in bearings 8, 8 onthe sides 9, 9 of the feed table. The roller shafts are provided withspur drivig gears 10 through which the feed rollers '7 are posi tivelydriven, to deliver the pipe slrelp, sheet or tin bars or other materialbeing rolled (not lengthwise, while lying side by side on the rollers 7which is the position in which the materials are delivered to theconveyer formed by the feed roller table.

Positioned between the pinch rollers 2 and 3 and the end roller 7 of thefeed table, with its ends secured to the supports for the pinch rollersand the rollers of the feed table, is an apron plate 11 having a wearingplate 11 and mounted on' each side of this apron plate 11 to extendabove the apron plate is a series of anti-friction rollers 12.

- on the other side of the apron plate. As

faces of the rollers 12 at apron plate 11.

shown slotted openings 15 in the apron plate for the securing bolts 16afford means enabling the necessary adjustment of the bracket bearings12 and rollers 11 to be made.

As will be seen in Fig. 1, the path defined by vertical planes tangentwith the opposite peripheral surfaces of the vertical rollers 12 istapering and converges toward the pinch rollers 3 and 4 and the pair ofopposite rollers 12 nearest the pinch rollers 3, at are adjusted adistance apart equal to or slightly greater than the width of theparticular size of pipe skelp or bars 17, 18, being rolled and tobesheared, while the end pair of opposite rollers 12 nearest theadjoining end of the feed table or conveyor formed by the rollers 7 areseparated a distance equal to or substantially equal to the combinedwidth of two, three or more of the bars being rolled.

The opposite pairs of the intermediate rolle'rs,l1 are set adistanceapart so that the periphery of these rollers will tangent straight linesdrawn tangent with the surthe ends of the In the operation of improvedmechanism, the pipe skelp 17-18 which are de livered upon the rollers 7of the feed table or conveyer while lying side by side as shown in fulllines in Fig. 1, are caused to travel endwise by rotating the feedrollers 7.

i As the front ends of the skelp 17 and 18 contact with the first of thepairs of vertical rollers 12 they are moved sidewise and as the frontends advance the skelp 17, 18 are gradually pushed sidewise until theyoverlap. The skelp, being thin and flexible, one will be lifted bycontact with the edge of the other and by. engagement with the verticalrollers 12 and lifted so as to be gradually moved sidewise in thecontinued lengthwise movement thereof so that whea -the forward ends ofthe skelp reach a position between the pinch rollers 3, at the two ormore skelp 17, 18 will be piled one on another so as to in combinationmeans move as a unit in further endwise movement. In the furtherlengthwise movement of the now piled materials, which movement iscontrolled by the intermittently rotated pinch rollers 3 and at, thepiled skelp are brought into the successive shearing positions necessaryto crop and cut the materials into pieces of the desired length. Theskelp beingpiled one on another, each shearing operation severs aplurality of pieces of skelp so that the time required in cutting thematerials into sheared lengths is greatly lessened. The above describedoperations are then repeated with succeeding lots of the materials.

The advantages of my invention will be an apparent to those skilled inthe art. Instead of piling the skelp by hand, which is slow andexpensive, the skelp are automatically piled one on another intoposition to be simultaneously cut to length while being moved intoposition to be sheared. By piling the skelp one on top of another, aseries of the skelp will be cut to length in the same time intervalrequired in shearing a single skelp while the simultaneous shearing ofthe series of bars may be accomplished with a shear having knives ofless width than the combined width of two pieces of the material beingsheared.

The apparatus is simple in repair.

Modifications in the construction and arrangement of the parts may bemade without departing from my invention as defined in the appendedclaims.

I claim:
